— A new dissipative method to design observers for a large class of nonlinear systems has been introduced recently by the author. It generalizes and includes several wellknown ob...
This work presents a set of cascade high gain observers for triangular nonlinear systems with delayed output measurement. A sufficient condition ensuring the exponential convergenc...
